Mars Global Surveyor celebrated its 10th anniversary on November 7th in silence.

"The spacecraft has many redundant systems that should help us get it back into a stable operation, but first we need to re-establish communications," project manager Tom Thorpe said in a NASA news release November 7th.

If communication cannot be restored, the team may try to diagnose the problem by having another spacecraft, the Mars Reconnaissance Orbiter, take pictures of the Mars Global Surveyor, to assess the condition of the MGS.
